1996 s-10 rear end

So. I have a 1996 chevy s-10 LS truck. Always wanted one. Just picked it up a few days ago. When going 45 or over i start to hear this friction comeing from the back of my truck. My friend says hes almost positive its the rear end. given that it leaks as well. Sooo i made a quick bull**** fix and put more fluid in there. It still sounds like its grinding. So now im onto replacing the whole rear end. I measured and unless im crazy the gasket size is like 8 and a half inch. This is a 4x2 rear wheel truck. Now ...

My question to you men is wich rear end can i put on there. I found a 1996 chevy s-10 extended cab parts car that does not run but they would be willing to sell the whole car for 175. So will the rear end from this truck fit onto mine? i heard somewhere that the extended cab is a 4x4 wheel drive truck..will this work for me? im open to anything guys...If another rear end will fit my truck from another truck or car then great. Id also like to get a beefier one if possible as well :-) Thanks in advance!!

Re: 1996 s-10 rear end

I believe that the extended cab uses a different yoke on the rear end. Be sure to check that out before you buy it. The noise that you hear could be a bad pinion bearing. This will cause the pinion seal to leak.

Re: 1996 s-10 rear end

So this 96 s-10 extended cab has the same engine as mine and its 2 wheel drive just like mine. All i need now is 2 find out if the rear end will work for mine. Its a real drive out to where it is so im trying to save myself a trip if i can. Also if possible i know my rear end code and all that : GT5 4.10 ratio is that all i need to match my rear end with another. what else needs to be matched?

Re: 1996 s-10 rear end

It will work.
If the yoke is diffrent swap it out as well.
If you want to make sure and don't believe people on here, just a get a measuring tape and measure it flange to flange.
Some have dampeners some don't.
I'm in the process now of getting the money to pick up a rearend for my 95 ext cab. I'm going to get one from a single or ext cab "standard" tranny truck because they are GT4 373 gea rear ends. Mine is automatic and has a 410 gear that's leaking like shit and rumbling.

Re: 1996 s-10 rear end

well paying 175 bucks for a parts car cant be bad when id pay 275 just for the rear end at a junk yard!!!! So thanks for the help guys. Also if it helps to diagnose my problem any better. The Grinding noise i hear from my rear end is almost constant at higher speeds but at lower speeds i only hear it when i let off the gas. If i accelerate its fine but when i let off...for about a second or 2 after you can hear it grind and then stop

Re: 1996 s-10 rear end

Any of you who have the 4.10 gears and want to get rid of them, please let me know. I build rear ends for some dirt track cars and I need some used 4.10 gears for them. I also need some used 3.23 gears.

Re: 1996 s-10 rear end

Are they usable? A little noise isn't going to bother these guys, but they need to hold up to racing. Give me a price and shipping cost and I'll see if they are interested.


http://www.s10forum.com/forum/f13/dr...ctures-410171/ Look at the pictures in this post and you will see the different yoke on the extended cab rear end. It has a round flange with bolts that hold the CV joint on. This would need to be changed to use this rear end in a standard cab truck.

so would i just need to swap the yoke from the extended cab and replace mine with it to make it work? Sure mine still runs..i described it above as best i could. Whats a reasonable price for it? junkyards woulda charged me 275 for a proper one.....say 100 excluding shipping?

Re: 1996 s-10 rear end

I'm in KY.

All I need is the ring & pinion gears. I don't need any of the other parts. The gears are going in G body rear ends. They use TH350 transmissions running in second gear. I need about 3 sets of usable 4.10 gears. These guys are on a tight budget and need good used cheap parts. I'm not marking anything up for them because they are old friends and need all the help they can get.

Re: 1996 s-10 rear end

Re: 1996 s-10 rear end

I don't know of any reason that it wouldn't work. Other than the yoke I don't know of any differences between them, as long as they are both 2WD or 4WD.

Re: 1996 s-10 rear end

Do you have pics of rear end? Do the axle tubes bulge just as they come out of the center section and then slim down? Like this? Not all ext cabs had the round four bolt pinion flange...just the ones with the double cardan style drive shafts..So if the donor truck doesn't have a double cardan style shaft then it will be a normal strap style pinion yoke. ALL 2wd rears 54.5" Wheel Mounting Surfaces...Doesn't matter ext cab or not..2.2 or 4.3..All year model 2wds are 54.5" WMS no matter what...... The only thing different would be the flange to flange between a disc brake rear or a drum brake rear but still both with a 54.5" WMS...Anyways here's the pic..Check to see if your axle tubes look like this:

Re: 1996 s-10 rear end

Thanks for the extended response petro!

Instead of going through the process of taking the entire axle off of the donor car and putting it on mine...i was wondering if id just be able to take off the rear differential and replace any broken gears. This 96 has got a lot of rust anddddd i truly dont have the time, money, or motivation to remove all the rusted parts. Some guy at a shop told me it couldn't be done by a DIY and that it had to be done at a shop. Is this true...or are they just trying to get some money out of me. I have a pretty good sense on cars...I've just never had to replace a rear end before.

Re: 1996 s-10 rear end

If you are talking about removing the ring & pinion and putting them in another housing then you are going to need a few special tools and some special knowledge. You will have to know how to set the pinion depth, bearing preload and backlash. You will need to know how to read the contact pattern so that you will know what adjustments need to be made to the pinion depth.

If you are just going to replace the differential then you will still need to check the backlash before removing the original and then set it back to the same number with the new differential.
